The cavity 42B may have a plurality of electrical contacts 42C-42F that may couple various electrical contacts 43C-43F of the external power source mechanical interfaces 43A, 43B. In an embodiment, the external power source mechanical interfaces 43A, 43B may be configured to couple to an external alternating current (AC) power source where power characteristics of the external AC power source may vary geographically as well known to one of skill in the art, e.g., the operating voltage may be about 100, 110, and 220 volts. In order to prevent potential damage to AC powered devices, different external AC power sources may require different mechanical interfaces (44A, 44B).

The TMM 67A may be any device capable or communicating data in one or more data communication formats including wireless and wired formats. Referring to FIG. 10, the TMM 67A may be included in an EDPDC apparatus 520A. The EDPDC apparatus 520A may be part of a wireless architecture 902 that may include one or more wireless or wired devices 30A to 30D and a wireless data or voice provider base station 904. In an embodiment the EDPDC apparatus 520A may include a TMM 67A and antenna 67B coupled to the TMM 67A. The TMM 67A may include a transceiver and modem that may communicate digital data or voice signals with one or more electronic devices (30A to 30D) and the digital data and voice signal base station 902. The base station 904 may be part of a larger network that may communicate with other base stations, electronics devices 30, EDPDC apparatus 520A 500A, 500B, 500B, 520B, 140A, 140B, 240A, 240B, 340A, 340B, 640A, 640B, 700, 800, 900A, 900B, 900C, computers, and networks of networks (commonly termed the “Internet”). In an embodiment the base station 904 may communicate data with the EDPDC apparatus 520A TMM 67A using one or more known digital communication formats including a cellular protocol such as code division multiple access (CDMA), time division multiple access (TDMA), Global System for Mobile Communications (GSM), cellular digital packet data (CDPD), Worldwide Interoperability for Microwave Access (WiMAX), satellite format (COMSAT) format, and local protocol such as wireless local area network (commonly called “WiFi”) and Bluetooth.

In an embodiment, the EDPDC apparatus 520A TMM 67A may communicate digital signals with the base station 904 using a first digital communication protocol and the electronic devices 30A to 30D using a second, different communication protocol. For example, the EDPDC apparatus 520A TMM 67A may communicate with the base station 904 using a cellular protocol such as code division multiple access (CDMA), time division multiple access (TDMA), Global System for Mobile Communications (GSM), Worldwide Interoperability for Microwave Access (WiMAX) or COMSAT protocol and communicate with the electronic devices 30A to 30D using a local protocol including WiFi and Bluetooth.

As known to one skilled on the art the Bluetooth protocol includes several versions including v1.0, v1.0B, v1.1, v1.2, v2.0+EDR, v2.1+EDR, v3.0+HS, and v4.0. The Bluetooth protocol is an efficient packet-based protocol that may employ frequency-hopping spread spectrum radio communication signals with up to 79 bands, each band 1 MHz in width, the respective 79 bands operating in the frequency range 2402-2480 MHz. Non-EDR (extended data rate) Bluetooth protocols may employ a Gaussian frequency-shift keying (GFSK) modulation. EDR Bluetooth may employ a differential quadrature phase-shift keying (DQPSK) modulation.

The WiFi protocol may conform to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol. The IEEE 802.11 protocols may employ a single-carrier direct-sequence spread spectrum radio technology and a multi-carrier orthogonal frequency-division multiplexing (OFDM) protocol. In an embodiment, one or more electronic devices 30A to 30D may communicate with the EDPDC apparatus 520A TMM 67A via a WiFi protocol.

The cellular formats CDMA, TDMA, GSM, CDPD, and WiMax are well known to one skilled in the art. It is noted that the WiMax protocol may be used for local communication between the one or more electronic devices 30A to 30D and the EDPDC apparatus 520A TMM 67A. The WiMax protocol is part of an evolving family of standards being developed by the Institute of Electrical and Electronic Engineers (IEEE) to define parameters of a point-to-multipoint wireless, packet-switched communications systems. In particular, the 802.16 family of standards (e.g., the IEEE std. 802.16-2004 (published Sep. 18, 2004)) may provide for fixed, portable, and/or mobile broadband wireless access networks. Additional information regarding the IEEE 802.16 standard may be found in IEEE Standard for Local and Metropolitan Area Networks—Part 16: Air Interface for Fixed Broadband Wireless Access Systems (published Oct. 1, 2004).

Further, the Worldwide Interoperability for Microwave Access (WiMAX) Forum facilitates the deployment of broadband wireless networks based on the IEEE 802.16 standards. For convenience, the terms “802.16” and “WiMAX” may be used interchangeably throughout this disclosure to refer to the IEEE 802.16 suite of air interface standards.

Otherwise the method 402B may determine whether a predetermined time interval has passed (sleep timer zero) activity 448B. When the time interval has not passed then the external power source may be decoupled (activity 454B) to reduce un-necessary power consumption. When the predetermined time interval has passed (sleep timer zero), the method 402B may determine whether the storage element 56A, 56B needs charging by comparing its storage level to a predetermined level or percentage of total capacity (activity 452B). When the storage element 56A, 56B internal level is less than the predetermined level or percentage, the method 402B may charge the storage element (activity 414C). The method 402B may then decouple the external power source (activity 454B) to reduce un-necessary power consumption and reset the sleep timer to the predetermined level or time (activity 440B).

The Abstract of the Disclosure is provided to comply with 37 C.F.R. §1.72(b), requiring an abstract that will allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In the foregoing Detailed Description, various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted to require more features than are expressly recited in each claim. Rather, inventive subject matter may be found in less than all features of a single disclosed embodiment.
